 u-blox message Sync A char
static const uint8_t DEFAULT_SYNC_B = 0x62
 u-blox message Sync B char
static const uint8_t kChecksumLength = 2

Detailed Description

This file defines the Serializer template class which encodes and decodes specific message types. The Reader class decodes messages and from a buffer and the Writer class encodes messages and writes them to a buffer. It also declares macros for declaring Messages. The Message class maps ROS messages types to class and message ID(s).

This namespace is for u-blox message serialization.
